Nice in parts. Went anti clockwise so to get the long road out of the way. The route then took us through the golf course which requires following the red line on the phone very carefully as there is no path and it rather alarmingly took us across two fairways where fortunately no one was playing a shot. Then back onto busy roads and so the first 30 minutes was not great. After that it was mainly pretty countryside interspersed with occasional bits of motorway and A road. Going anticlockwise means the one big steep hill is down rather than up.
At the end there was a sense that you never really properly escaped the metropolis but it had its moments.
